SOLVED Boot Ubuntu 20.04.3 UEFI + Preseed = Error cannot verify [...] certificate issued by CN=FOG Server CA


  • Hi there.

    First i need to thanks all team,devs and enthousiats volounteers participating and helping this great project.

    I managed to boot Ubuntu 20.04.3 via NFS/HTTPS with UEFI (BTRFS + apt-btrfs-snapshots) (LUKS OR NOT) with a fully automated preseed/postinstall.sh

    Here are the files :

    The menu :

    # Il s'agit d'automatiser une installation d' Uuntu 20.04.2 Desktop à destination des desktops et laptops du mouvement.
    # Certaines informations manquent et des tests sont en cour.
    # On pourrait utiliser Packer , Vagrant, Ansible , toussa mais pour le moment on fait un preseed assez simple sans jonction à l'AD mais avec les
    # paquets qui vont bien.
    # On pourrait aussi utiliser autoinstall du cloud-init en yaml mais c'est compatible uniquement avec la version server . Pourquoi ? je n'en ai absolument aucune idée.
    # À terme nous prevoyons deux autres preseed apres des tests: 
    # Un pour des laptop (chiffrement luks)  avec/sans jonction AD
    # Un pour machines virtuelles avec jonction AD
    # Enjoy !

    ## Partitioning example
    # If the system has free space you can choose to only partition that space.

    # Alternatives: custom, some_device, some_device_crypto, some_device_lvm.

    # Alternatively, you may specify a disk to partition. If the system has only
    # one disk the installer will default to using that, but otherwise the device
    # name must be given in traditional, non-devfs format (so e.g. /dev/sda
    # and not e.g. /dev/discs/disc0/disc).
    # For example, to use the first SCSI/SATA hard disk:
    #d-i partman-auto/disk string /dev/sda
    # In addition, you'll need to specify the method to use.
    # The presently available methods are:
    # - regular: use the usual partition types for your architecture
    # - lvm:     use LVM to partition the disk
    # - crypto:  use LVM within an encrypted partition
    d-i partman-auto/method string regular
    
    # If one of the disks that are going to be automatically partitioned
    # contains an old LVM configuration, the user will normally receive a

    # And the same goes for the confirmation to write the lvm partitions.
    #d-i partman-lvm/confirm boolean true

    ### Preseeding other packages
    # Depending on what software you choose to install, or if things go wrong
    # during the installation process, it's possible that other questions may
    # be asked. You can preseed those too, of course. To get a list of every
    # possible question that could be asked during an install, do an
    # installation, and then run these commands:
    #   debconf-get-selections --installer > file
    #   debconf-get-selections >> file
    
    
    #### Advanced options
    ### Running custom commands during the installation
    ## i386 Preseed Example
    # d-i preseeding is inherently not secure. Nothing in the installer checks
    # for attempts at buffer overflows or other exploits of the values of a
    # preconfiguration file like this one. Only use preconfiguration files from
    # trusted locations! To drive that home, and because it's generally useful,
    # here's a way to run any shell command you'd like inside the installer,
    # automatically.
    
    
    # This command is run immediately before the partitioner starts. It may be
    # useful to apply dynamic partitioner preseeding that depends on the state
    # of the disks (which may not be visible when preseed/early_command runs).
    #d-i partman/early_command \
    #       string debconf-set partman-auto/disk "$(list-devices disk | head -n1)"
    
    # This command is run just before the install finishes, but when there is
    # still a usable /target directory. You can chroot to /target and use it
    # directly, or use the apt-install and in-target commands to easily install
    # packages and run commands in the target system.
    #d-i preseed/late_command string apt-install zsh; in-target chsh -s /bin/zsh

    It worked like a charm on Debian 10.11 with FOG 1.5.9

    I tried the exact same configuration on Debian 11.2 with FOG 1.5.9.114

    I got this error on the client :

    Error cannot verify [...] certificate issued by CN=FOG Server CA

    and this in apache2 logs :

    10.17.1.220:80 10.17.3.171 - - [07/Jan/2022:10:58:05 +0100] "GET /autoinstall/ubuntu/ubiseed_20_vm.cfg HTTP/1.1" 302 563 "-" "Wget/1.20.3 (linux-gnu)"
    

    EDIT : Forgot to say i can DL the file from a client on the network with :

    wget --no-check-certificate https://10.17.1.220:/autoinstall/ubuntu/ubiseed_20_vm.cfg
    

    i got :

    Wich means it could’nt verify the self signed attribute but however result with a 200 OK .

    I thought it can be some minor changes i need to do and looking for a clue or some good advice here.

    Thanks fellows.

    Have a nice day.


  • @george1421 : Thank you very much.

    In fact i’m used to regular pxe server and we use fog mostly for the cloning feature for windows Workstations.

    To deal with Ubuntu workstations i like to do iso booting + pxe , this way i can mix/test configurations (preseed.cfg) of installation process quickly/easily directly from our gitea.

    By the way i use fog as the main pxe server even for servers with debian based installations.

    After this part of deployment ansible is the king of the hill to do all basics/complex tasks.

    Can i modify the topic’s title with SOLVED ? Can i edit my posts to remove the domain’s informations ?

    Regards.

    @fogman4 Your english is fine, maybe better than I. I could just read your post a few different ways since I know nothing of your setup that is why I asked. Trying to build a truth table, it wasn’t clear what changed in your environment.

    Great you found the solution because I could tell it was going to be a difficult one to debug. Well done on working out the problem!


  • @george1421 : Hi George

    Thank you for your response as always it’s fast and relevant.
    As you notice english’s not my native language i’ll try to be clear.

    1. There are 2 differents servers: old one (deb10) and new one (deb11) . I installed a fresh new Debian 11 OS on a VM to do some tests on another facility. I keep the older (debian 10) fog server on the main site.
    2. Debian 11 is the OS of the FOG server 1.5.9 119. The target comptuter is booting a ubuntu 20.04.3 iso via NFS.
    3. I’m automating installing Ubuntu 20.04.3 with (debian) preseed which works like a charm on the older server. I’m not confortable with doing image capture/deploy with ubuntu. I want to keep control over specific setting for several workstations whithout doing a capture/deploy cycle each time i do some tests.

    You’re right it’s a redirection and you know what ? I’m a complete dumbass :

    diff 001-fog.conf 001-fogm.conf

    I got the exact same problem few times ago and you and @Sebastian-Roth already helped me out !

    Right here :

    https://forums.fogproject.org/topic/15760/uefi-boot-pxe-preseed-ubuntu20-04-via-nfs-with-https-preseed?_=1641557754413

    I just adapt the the apache conf of new FOG and it works perfectly ! Now i just feel stupid.

    Thank you very much and sorry for the convenience.

    Best regards.

    @fogman4 While I don’t have an immediate answer for the certificate issue I see you changed 2 things.

    1. You went from fog 1.5.9 to 1.5.9.114. Is that on the same fog server with no other changes to the FOG server? Or did you build a new fog server with the updated version of FOG?
    2. Is Debian 11 the OS you are using for your target computer or your FOG server?
    3. It looks like you are automating building Debian using FOG via netbooting and not FOG imaging?

    If the only thing that changed is Debian 11 (upgrading from 1.5.9 to 1.5.9.119 can be ignored for the moment) I would say that Debian 11 has tighter controls on https communication where it probably needs the FOG self signed root certificated added to the trusted certificate store. That is kind of what the error is telling me assuming nothing else changed other that what you are building on the target system.

    The error message is interesting too. Error 302 is a redirect for sending the browser some place else. Also look at the very beginning of the error message. 10.17.1.220:80 how did port 80 (HTTP) get in there? You are using https everywhere in your scripts??

    10.17.1.220:80 10.17.3.171 - - [07/Jan/2022:10:58:05 +0100] "GET /autoinstall/ubuntu/ubiseed_20_vm.cfg HTTP/1.1" 302 563 "-" "Wget/1.20.3 (linux-gnu)"
